To all whom i may concern:

Be it known that I, Amos B. BUCKLAND, a citizen of the United States,residing et Rochester, in the county of Monroe and State of Xew York,have invented certain This invention relates to improvements Yincandescent -lam holders, whereby said' lamp may be belt in any desiredposition, means being provided whereby the 'holder may be quicklyadjusted to change the position of the lain A further ob ect is toprovide means for at taching the holder in various positions to theceiling or side walls of a room or to e. desk.

'ith the above and other objects in view the invention consists ofcertain novel features of construction, combination, and nrranfement ofparts. as will be hereinafter described and claimed.

in the accompanying drawings, Figure 1 is a side view oi the bracket,showing the saine attached to a ceiling and supporting a lamp, Fig. 2 isa similar view of the opposite side of the holderparts of thebracket-arm being broken away. Fig. 3 is an edge view of the saine. Fig.4 is n detail side view of the attaching end ot' the bracket, showingthe nnmner of connecting thesanle to a desk. Fig. 5 is a similar viewshowing the manner of connecting the attaching end to a gi1sburner. Fig.6 is a similar view showing the manner of connecting the saine to s wallor side bracket.

Referring more particularlv to the drewings, I denotes a supporting-arm.which is adapted to, be pivotally connected on the lower end of abracket '3, seid lnncl ct.being secured to the ceiling or side wall of aroom or to a desk or other support. n the supporting'arm 1 is formed utoothed segment l, and in the center of said segmental portion of thearm is arranged a lateraliv-projecting headed stud 4, on which isslidablv and pivotally mounted a right-angulnriy-formed connecting-bnr5. Suid har is provided with a slot 6, whereby the saine is slideblyconnected with the stud 4, as shown. One end of seidright-angularly-formed connecting-bar projects n short distance beyondthe upper edge of the toothed segment 3, and on said pro-Ysuppnrting-rsIne 1s arranged a laterallynnivotally connected thereto beeting sufi. of` the bar is arranged a laterallyprojeeting stud 7", andwhen thebar 5 is moved upward on the pivot-stud 4 said stud 2.xisfdisengaged from the teeth vof the segmental rack 3, and the bar canthen be moved on the pivot 4 to either of the posiV tions shown in Figs.and 6, and then said stnd? X* ney be engaged with one of the teeth ofsaid segmental rack or toothed segment, 3,

thereby holding said right-nngelindy-formed.J

eonneegtfng-bsr at. venons angies withrespent' to the supporting-frame.0n said protecting stud 8, against. which the bar 5 is adapted tostrike, thereby limiting the movement of said bar in one direction.

in the longer end of the bei* is formed a longitudinally-disposed slot9,' through which s. stud 7 projects, and to seid end of the bar ispivotally connected the inner end of an ed instable supportingerni 10,said arm being in the forni of lszytongbars 12. To the outer end of thearm 1t) is'pi'votslly ernmentO ed a lain fholding arm or bar 13, theinner end of w `eh is provided with s longitudinally-disposed slot i4,through. which is ada'pted to project a guide-screw 15, said screwforming the central pivotal connection of one pair of the lszv-tong bars12. On the outer end of the guide-screw l5 is screwed a clamping-nut 16,Vsaid nut being adapted to be screwed into tight engagement with theslotted end of the erin or bar 13, thereby holding or locking thelazy-tong bars in their adjusted position, and thus holding thesupporting-arm 10 in an extended or retracted position,

The Verin or ber 13 has preferably formed therein e right-angularotiset, and to the end of said o'set portion of the bar is pivotallyconnected a'lenipdiolding clip 17. Said clip consists of s air ofspring-arms 1S, the outer ends of whic i are connected bei s coil-s ringit), thereby affording an adjustable vie dingr holding device for thelamp. Bhe clip 17 is insulated from the end of the erm 10 and is meansof a screw 2t), which passes throng the clip and the end of the bar andis rovided with a clamping-nut 21, whereby t e same :nay be held rigidlyat various angles, thus permit ting the lamp to be supported in anydesired position. To the supporting-arm 1 is secured a wire-holdingdevice 22, said device being preferably in the form of a clip,consisting of curved spring-metal arms which are IOC preferably coveredwith a suitable insulated material.

By means ot a supporting device such as herein shown and described anincandescent lamp or other articlt` may he supported vin variouspositions. means being provided whereinY said supporting device ma)v beattached to a ceiling, as shown in Fig. 1, or to a desk, as shown inFig. 4, in which instance a suitable clamp or attachiinr device 3 isprovided to connect the brachet 2 to the desk, means being also provided\vhei'eh \v the supoEting-bracket may be connected to a gasurner, asshown in Fig. 5, or to a side wall, as shown in Fig. ti.

Front the foreeoing description, taken in connection with t teaccompanying drawings,

.the construction and operation of the invention Will be readil)vunderstood without 4rcquiring a more extended explanation.

Various changes in the form, proportion,

and the minor details of construction may be resorted to withoutdeparting from the prin- 'ciple or sacrificing any of the advantages ofthis invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letl15ers Patent, is-

1. In a holder of the character described, thei combination `.Vith anattaching-bracket, o a supporting-arm pivotall)v mounted on Saidbracket, a toothed segment; formed on -said arm, lazy-tong bars, aslotted right-angularly-fornied connecting-bar adapted to pivotallyandadjustably connect said lazyton bars to said supporting-ar1n, means forhol ing said connecting-bar in adjusted position, and a lamp-ho1derconnected to the opposite end of said lazy-tong bars, substantla ly asdescribed.

2. In a holder of the characterldescribed. the combination with an'attacliing-lnacket, of a supporting-arm pivotall)` mounted on saidbracket., a toothed segment formed on saidarni lazy-tong bars, a slottedright-angularly-torzued connecting-bar to pivotally and adjustabljYconnect said lazy-tong bars to said supporting-arm, a stud arranged onsaid connecting-bar to engage the teeth on said segment, thereby holdingAsa-id lazv-tmw bars at dill'crcnt angles. a lamp-holder pivotalllvmounted on thc opposite cnd of said lazy-tong bars, and means to holdthe latter in their adjusted position, substantiall)Y as described.

3. ln a holder of the character described. the combination with anattaching-brzwltct. of'a supporting-arm pivotaliv mounted on saidbracket. a toothed segment formed on said armv lazy-tong bars, a slottedright-angularlvformcd connecting-lair to pivotallv and adjustabhvconnect said lazy-tong bars to said supportingmrm. a stud arranged onsaid connecting-bar to. engage. thc teeth on said segment, therebyholding said lazy-tong bars at dillercnt angles, means arranged on saidsupporting-plate toV limit the movement of said connecting-bar in onedirection, a slotted locking-har arranged on thc outer end of said la'/.v-tong bars. means in connection with said locking-bar to secure saidlazy-tong bars in adjusted position, a lamp-holdcr pivotall connected tothe outer end ol' said locking-bar. substantiall \v as described.

4. ln a holder of the character described, the combination with anattaching-bracket. of a supporting-arm pivotall \Y mounted on saidbracket, a toothed segment formed on said arm, laz \tong bars. a slottedrightaingularlv-formed connecting-lair to pivotall)Yand-adjustably`connect' said lazy-tong hars to said supporting-arm, astud arranged on said conncctingsbar to engage thc teeth on saidsegment, thereby holdingr said lat-tong hars at ditlcrentat1glcs.aslottcd locking-har arranged on the outer end of said lazy-tongbars,` a locking-screw and nut to engage the slot in said locking-bar, aspringsholding clip ivotallv mounted on the ou'tcr cnd of saidocltingbar, and a spring-metal. wire-.supporting clip connected to saidsupportingplate. substantiall \v as described.

ln testimony whereof I have hereunto set in v hand in presence of twosubscribing witnesses.
